512mb TT-RAM and 14mb ST-RAM. Sometimes I get a black screen when I start it and sometimes I can arrow one menu item down before It hangs and I have to do a hard reset to get back on track. I run my CT63 at 90mhz usually, but tried 66mhz when I experienced the hangups just to be on the safe side.

Dal: I do have the SV clock lines soldered in place. I don't know what you mean by clock patch though. Can you elaborate?Is it the mod mentioned on Rodolphes site?Other regular Falcon games and patched ST games works like they should, as well as demos. Just that Natcar wont work.

Will record a clip of what happens when I try to start it and put it on youtube. Might make it easier to diagnose.

Knezzen, I think you should try the new FW11 variants, because I think you may have a SV FPGA that is too close to its timing limit, and that problem only shows up when you run Natcar that uses heavy blitting.

Seems to me whenever all the other cars are on the screen it starts to slow down. I'd also like to know why xboot is all garbage until I move the mouse over things... Not sure if everyone's SuperVidel does that, or I'm just special.

It's weird, I had tried the Worms port on my falcon and couldn't get it passed the TSCC intro, but then when I correctly installed the VGA sync cable to the SuperVidel now it works fine, so maybe I'll make a video of that next.

Hmm, interestingly when I put both before xboot (or simpleboot) I get a white screen of nothing (checked both DVI and VGA, though didn't check the Videl output). But if I just but the SV_XBIOS.PRG in front of xboot, it shows up fine. Granted that causes it to either load SV_XBIOS.PRG twice, or something else is crashing, though the desktop shows up fully, so I'm not sure what that is.
